Variateur Danfoss VLT Micro Drive FC-051P4K0T4E 4 kW

Product Overview

The 132F0026 (132F0026) is a highly compact and efficient VLT® Micro Drive FC-051, engineered by Danfoss to provide maximum reliability and ease of use in general-purpose motor control applications. Delivering 4.0 kW (5.5 HP) of power, this three-phase frequency converter is optimized for industrial machinery such as conveyors, pumps, and fans where cabinet space is at a premium. Despite its small footprint, the FC-051P4K0T4E is built with heavy-duty components, including coated PCBs and a built-in brake chopper, ensuring high performance and longevity even in demanding environments. Its sophisticated VVC+ control logic provides excellent motor shaft performance, significantly improving process precision and reducing energy waste across the automation lifecycle.

Technical Configuration

The VLT® Micro Drive platform is designed for side-by-side mounting without derating, maximizing panel density. This specific unit operates on a 380 - 480 VAC supply and features an H3 RFI filter, providing high-level electromagnetic compatibility (Class A1/B). A critical hardware advantage is the factory-integrated Brake Chopper, which allows the drive to manage regenerative energy during rapid motor deceleration, protecting the DC link from overvoltage. The inclusion of Coated PCBs (C Option) provides an essential layer of protection against moisture and airborne contaminants, making the 132F0026 a superior choice for industrial settings. The drive supports up to 5 programmable digital inputs and dual analog inputs, allowing for versatile control configurations directly from the terminal block.

Technical FAQs

Does the 132F0026 include a local control panel (LCP)?

No, this specific code is supplied without an LCP (indicated by the 'X'). For manual operation or local parameter adjustment, a VLT® Control Panel LCP 11 (without potentiometer) or LCP 12 (with potentiometer) must be ordered separately and plugged into the front interface.

What is the benefit of the VVC+ control mode?

VVC+ (Voltage Vector Control Plus) is a Danfoss-patented control principle that ensures the motor develops full torque at low speeds and responds rapidly to load changes. It provides near-servo performance for standard induction motors, enhancing the efficiency of the 4.0 kW output.

Can this drive be mounted horizontally?

For optimal cooling, the drive must be mounted vertically. The IP20 enclosure relies on natural or forced convection through the heatsink. Vertical mounting ensures that the 194 mm height of the unit acts as a chimney, pulling cool air from the bottom and exhausting heat from the top.

Engineering & Installation Guide

• Brake Resistor Selection: Since this unit features a built-in brake chopper, you can connect an external brake resistor to the BR+ and BR- terminals for applications requiring fast braking or frequent stops. Ensure the resistor value (Ohms) matches the drive’s 4 kW specifications to avoid damaging the internal chopper circuit.

• PCB Protection & Environment: The coated PCBs in this model offer enhanced resistance to pollution degree 3 environments. However, ensure that the cabinet ventilation is filtered to prevent the buildup of conductive dust on the terminal blocks, which are not coated.

• Cable Routing: Maintain a minimum distance of 200 mm between the motor cable and the control/signal cables to prevent electromagnetic crosstalk. Use shielded motor cables and ensure the shield is connected to the ground plate at the drive end using a high-frequency (HF) clamp to comply with the H3 RFI filter standards.
